Abstract

L'invention concerne un procédé pour charger un condensateur d'un circuit intermédiaire dans une unité de précharge. La charge du condensateur de circuit intermédiaire est effectuée par l'intermédiaire d'une source de courant dont le courant est réglé de telle manière qu'une puissance de perte constante est générée dans la source de courant durant tout le processus de charge. Par ailleurs, la présente invention concerne un circuit équipé d'une batterie (1) qui est reliée à une source de courant (2), cette dernière étant reliée au condensateur du circuit intermédiaire par l'intermédiaire d'un interrupteur (3). En parallèle à la source de courant (2) est disposé un circuit de régulation (5) avec lequel le courant servant à charger le condensateur du circuit intermédiaire (4) peut être régulé de telle manière qu'une puissance de perte constante est générée dans la source de courant (2) durant tout le processus de charge.
